Nickel uye Nickel Alloy Welding Electrode
Ni307-2
GB/T ENi6133
AWS A5.11ENiCrFe-2
Tsanangudzo: Ni307-2 is nickel-based electrode ine yakaderera-hydrogen sodium coating.Shandisa DCEP (yakananga ikozvino electrode yakanaka).Sezvo weld iine humwe huwandu hwemolybdenum, niobium uye zvimwe zvinosanganiswa zvinhu, simbi yakaiswa ine yakanaka kutsemuka.
Chikumbiro: Inoshandiswa kukwenenzvera nickel-chromium-iron alloys (senge UNS N08800, UNS N06600), kunyanya yakakodzera kuputika simbi dzakasiyana, transition layer welding uye welding yepasi, uye inogona zvakare kushandiswa kana tembiricha yekushanda iri 980 ° C, asi inogona kuramba oxidation kana tembiricha yakakwira kupfuura 820 ° C Kuderera kwebonde uye kusimba.
Kemikari yakagadzirwa nesimbi weld (%):
| C | Mn | Fe | Si | Cu | Ni |
| ≤0.10 | 1.0 ~ 3.5 | ≤12.0 | ≤0.8 | ≤0.5 | ≥62.0 |
| Cr | Nb + Ta | Mo | S | P | Zvimwe |
| 13.0 ~ 17.0 | 0.5 ~ 3.0 | 0.5 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.50 |
Mechanical zvimiro zve weld simbi:
| Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % |
| Guaranteed | ≥550 | ≥360 | ≥27 |
Yazvino inokurudzirwa:
| Tsvimbo dhayamita (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding ikozvino (A) | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Cherechedza:
1. Elekitirodhi inofanira kubikwa kweawa imwe panguva inenge 300 ℃ isati yaitwa welding;
2. Zvakakosha kuchenesa dzine ngura, oiri, mvura, uye tsvina pazvikamu zvinonamatwa tisati tapisa.Edza kushandisa arc pfupi kuti weld.
